The toxoplasmosis risk during pregnancy
Pregnant women should not clean the litter box because cat feces can carry toxoplasmosis, a parasitic infection caused by Toxoplasma gondii. Cats are the only animals that shed this parasite in their feces, and the parasite can survive in litter for weeks. If a pregnant woman inhales dust from contaminated litter or touches her face after handling litter, she can become infected.
Toxoplasmosis itself causes mild or no symptoms in healthy adults — most people who catch it never know they had it. But if you are pregnant and become infected for the first time, the parasite can cross the placenta and harm the developing baby. The risk is highest in the first trimester, though infection at any stage of pregnancy carries risk.
Key Takeaways
- Toxoplasmosis is a parasitic infection found in cat feces that can pass from a pregnant woman to her unborn baby.
- The parasite survives in litter for weeks and spreads through dust inhalation or hand-to-face contact, not through petting the cat itself.
- Infection during pregnancy can cause miscarriage, stillbirth, or birth defects including eye damage and brain damage in the baby.
- A partner, family member, or friend should clean the litter box daily, and the pregnant woman should wash her hands after any contact with the cat.
- If a pregnant woman has had toxoplasmosis before, she has immunity and the risk to the baby is very low.
How the infection spreads to the baby
When a pregnant woman first contracts toxoplasmosis, the parasite enters her bloodstream and can cross into the placenta. The risk to the baby depends on when during pregnancy the infection occurs. Early infection (first trimester) has a lower chance of passing to the baby but causes more severe damage if it does — including eye infections, brain damage, and developmental delays. Later infection (third trimester) passes to the baby more often but typically causes less severe harm.
The damage can include congenital toxoplasmosis, which may cause vision loss, hearing loss, intellectual disability, or seizures. Some babies show no symptoms at birth but develop problems later in childhood. Others are born with serious complications that require when ready medical care.
Why the cat itself is not the danger
You cannot catch toxoplasmosis by petting your cat, playing with it, or being scratched or bitten. The parasite lives only in the cat's intestines and is shed through feces. A cat that is kept indoors and eats only commercial cat food has a very low risk of carrying the parasite at all — outdoor cats and cats fed raw meat are at higher risk.
The danger is the litter box, not the animal. Even a cat that carries the parasite shows no signs of illness. You cannot tell by looking at a cat or its litter whether toxoplasmosis is present, which is why the safest approach during pregnancy is to have someone else handle litter duty entirely.
What happens if you have already had toxoplasmosis
If you contracted toxoplasmosis before you became pregnant, you have lifelong immunity. Your body has already built antibodies against the parasite, and reinfection is extremely rare. In this case, the risk to your baby is very low — your immune system will protect the pregnancy.
Your doctor can order a blood test to check whether you have immunity. If you are unsure of your history or have lived in a region where toxoplasmosis is common, a test before or early in pregnancy can tell you whether you need to take precautions. This information helps you and your doctor make informed decisions about litter box contact.
Safe practices if you must handle the litter box
If no one else in your household can clean the litter box, wear disposable gloves and a mask while doing so. Scoop litter daily — the parasite takes one to five days to become infectious in feces, so daily removal reduces risk. Wash your hands thoroughly with soap and warm water after removing gloves, and do not touch your face while handling litter or gloves.
Avoid touching your mouth, nose, or eyes until you have washed your hands. If you have a cut or scrape on your hands, cover it before handling litter. After cleaning, wash the scoop and litter box with hot water — the parasite dies at high temperatures. These steps reduce risk significantly, though having someone else do the work remains the safest option.
Other sources of toxoplasmosis during pregnancy
Litter boxes are the most common source of toxoplasmosis for pregnant women in developed countries, but undercooked meat is also a risk. Eating raw or undercooked beef, pork, lamb, or game meat can transmit the parasite. During pregnancy, cook all meat to safe internal temperatures: 160°F for ground meat, 145°F for whole cuts, and 165°F for poultry.
Unwashed vegetables and fruits can also carry the parasite if they were grown in soil contaminated with cat feces. Wash all produce under running water before eating. These precautions, combined with avoiding litter box contact, reduce your overall risk of infection during pregnancy.
When to talk to your doctor about toxoplasmosis
Tell your doctor that you have a cat at home during your first prenatal visit. Your doctor may recommend a blood test to check your immunity status, especially if you are in your first trimester. If you have symptoms that could suggest toxoplasmosis — such as fever, fatigue, muscle aches, or swollen lymph nodes — report them to your doctor right away.
If you accidentally handled the litter box or believe you may have been exposed, contact your doctor. They can order testing and, if needed, prescribe treatment. Antibiotics taken during pregnancy can reduce the risk of the parasite crossing the placenta, so early detection and treatment matter.
Frequently Asked Questions
Can I get toxoplasmosis from petting my cat?
No. The parasite lives only in the cat's intestines and feces, not on its fur or skin. You cannot catch it by petting, playing with, or being scratched by your cat. The only risk is direct contact with contaminated litter or feces.
What if my cat is indoor-only and eats commercial food?
Indoor cats that eat only commercial cat food have a very low risk of carrying toxoplasmosis. However, the risk is not zero — some cats can still carry the parasite. During pregnancy, the safest approach is still to have someone else clean the litter box, even if the risk is small.
How long does the parasite survive in litter?
The parasite becomes infectious in cat feces within one to five days and can survive in litter for weeks or even months under the right conditions. Daily litter scooping removes feces before they become infectious, which is why frequent cleaning reduces risk if you must handle the box yourself.
Can I catch toxoplasmosis from my cat's saliva or urine?
No. The parasite is shed only through feces. Saliva and urine do not carry toxoplasmosis. The risk comes only from contact with contaminated litter or feces.
Is it safe to have a cat during pregnancy?
Yes, it is safe to have a cat during pregnancy as long as someone else cleans the litter box and you follow basic hygiene practices. You can continue to pet, play with, and care for your cat in all other ways. The only restriction is litter box contact.
